Exactly. Also, the sprocket and the chain are spinning deep in oil so they should splash oil constantly all over, even if the oil level is below minimum. Another thing is, unlike ball bearing applications elsewhere, here the flange, inner ring and race are all stationary, so oil should crawl directly to the balls on the surface of not moving parts. Adding DOF to a ball bearing here makes no sense to me. It`s there already.
